ROBERT HENDERSON, OF THOMASTON, CONNECTICUT.

TURBINE.

To all whom it may concern:

Be it known that I, ROBERT HENDERSON, a citizen of the United States,residing at Thomaston, in the county of Litchfield and State ofConnecticut, have invented a new and useful Im rovement in Turbines; andI do hereby declare the following, when taken in connection with theaccompanying drawings, and the numerals of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in

Figure 1. a side View partially in section of a turbine constructed inaccordance with my invention. Fig. 2 a vertical sectional view of thesame. Fig. 3 shows two buckets one in side view and the other insection. Fig. 4 a top or plan view of two buckets, one being shown inbroken lines.

This invention relates to an improvement in turbines, and whileparticularly intended for use with steam, is equally applicable for.water, the object of the invention being a simple and effectivearrangement of parts and the invention consists in the constructionhereinafter described and particularly recited in the claims.

In carrying out my invention, the casing consists of a central ring 2and side shells 3 and 4. These shells are bolted to the casing which isprovided with feet 5 and. 6 by which it may be supported. This centralring and the shells form a steam chamber, and the sides 3, 4, are formedwith hubs 7 and 8 for a shaft 9. The ring 2 is formed at the top with aninlet opening 10 and at the bottom with an outlet 11 which intersects atransverse passage 12 which registers at opposite ends with ports 13 and14 formed in the respective sides 3 and. 4. Within the central ring andsecured to one of the shells is a nozzle ring 15. This ring has a seriesof nozzles 16 more or less in number and arranged tangentially to theshaft. Mounted upon, and keyed to the shaft is a bucket wheel 17carrying on its periphery a series of buckets 18. Preferably the numberof buckets will be half as many again as the number of nozzles.

Specification of Letters Patent.

Application filed May 17, 1909.

SeriaLNo. 496,519.

These buckets which form an important part of my invention, are castmetal buckets and provided with flanges 19 which are embedded in theperiphery of the wheel 17. Each bucket is formed with a transverselyrounded projecting nose 20 and each nose enters the next succeedinbucket. Or in other words, the buckets are formed by the spaces betweenthe several members. This particular form of bucket prevents Windage.Steam or water being admitted at the top through the opening 10 willfill the chamber, and passing through the nozzles 16 will enter theseveral buckets and force the wheel 17 to revolve. Having performed itsfunction, the exhaust steam or water will escape through the ports 18and 14 and out of the exhaust outlet 11.

It will thus be seen that I have provided an extremely simplearrangement of turbine which is particularly effective in operation.

I claim 1. A turbine comprising a casing, a nozzle ring mounted therein,and a bucket wheel. adapted to revolve and provided on its peripherywith a series of closely arranged buckets each bucket formed withbeveled edges adapted to be engaged with the rim of the bucket wheel andeach bucket having a forwardly projecting tapered nose.

2. A turbine comprising a casing formed from a central ring with shellssecured to opposite sides, a centrally arranged nozzle ring locatedbetween said sides and formed with a series of tangentially arrangednozzles, an inlet opening in the top of the central ring, outlets at thebottom of the sides, said outlets connecting with the outlet opening atthe bottom of the central ring, and a bucket wheel arranged within thenozzle ring and carrying a series of closely arranged buckets.

In testimony whereof, I have signed this specification in the presenceof two subscribmg witnesses.

ROBERT HENDERSON.
